Cleveland Codonics offered an add-on graphics card for the H/Z19 and H/Z89 systems call the Imaginator I-100.
- High resolution of 504 x 247 pixels (monochrome).
- Onboard microcomputer eliminates graphic processing load on host.
- Two modes of operation - ASCII and binary.
- They offered an option EPROM that allowed it to emulate a Tektronix 4010/4014.
A fully assembled and tested board sold for $445. In kit form it was $395. The Tektronix 4010/4014 emulation option was an additional $75. Mounting hardware needed for the H/Z-89 was an additional $20.
They also sold the related source code for $125.
I recently bought a H89 on ebay which contained the a Cleveland Codonics Imaginator board. The system was in poor condition and needs major cleaning and repair. I plan to have pictures and more details shortly.
Here is a scanned ad for the Imaginator I-100.
Still in business, now known simply as Codonics. The Imaginator was the company's first product and is on display in their office.
